The subject of life and death is often viewed in the context of light and dark. It is said that one of the greatest fears of human beings is the fear of dying. The great mystic Osho has written an entire book called “Let me teach you about death” (a highly recommended read by me). The Bhagavad Gita has many references to life and death – the nature of the body, the mind, the spirit – what truly dies and what can never die and many such discussions.
